Chunk: no such object

[Aminda O'Hare]

I am having trouble with a card stack that should load words from a  
text file into the field questions on the next card, however, when I  
click the button that should do this I get the following error:  
Chunk: no such object, Line: put it into field questions of next  
card, Hint: questions. The Application Browser shows that the field  
questions does indeed exist on the next card. I think that I've seen  
this kind of problem before and solving it involved typing a command  
into the message box, however, I cannot remember what that command  
was. Any help would be greatly appreciated.
Sincerely,
Aminda O'Hare
